FASTEN ER FOR THE M EETlNG-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 477,537, dated June 21,1892. Application filed November 13, 1891. Serial Ito/11,800. (Nomodel.)

T0 in whom it may concern:

Be it known that I, DAVID GUTERMUTE, of Petaluma, in the county ofSonoma and State of California, have invented certain new and usefulImprovements in Window or Sash Fasteners; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to a new and highly useful improvement in windowor sash fasteners; and it has for its object the production of a cheap,simple, and highly-efficient improved lock or fastener, whereby eitherone or both sashes of a window can be adjusted and held locked in anydesired position.

The invention comprises the detail construction, combination, andarrangement of parts, substantially as hereinafter fully set forth, andparticularly. pointed out in the claims.

In the accompanying drawings, Figure l is a view in perspective of aportion of a window with my improved fastener applied thereto. Fig. 2 isa view showing all the parts of the locking mechanism separated.

Referring to the drawings, A designates the upper sash of a window, andA the lower sash thereof. To one of the side bars of the upper sash A isrigidlysecured a plate at, having a series of openings a therein. To theupper horizontal bar of the lower sash is attached the locking mechanismB. The same comprises a movable bolt 0, the inner end of which isdesigned to enter any one of the series of openings at in plate a. Thisbolt is inclosed in a casing 79, attached to the lower frame by screwspassed through holes Z) in its bottom plate, and it is also providedwith a removable top plate b which has a flange b designed to projectinto an aperture in a curved or bulged portion of easing b. In one sideof bolt C are grooves or recesses forming shoulders (1 cl, with whichare designed to engage the inner ends of a pivoted catch or locking-headD. This catch D is pivoted by a hollow boss d projecting from the bottomof easing Z), and is held thereon by the top plate 12 the latter beingsecured by a screw d working in said boss. The narrowed portion of catchor locking-head D is projected out through the opening or aperture inthe curved or bulged portion of casing 11. A

plate-spring E, secured at its lower end to the lower sash, engages bolt0 and normally holds the latter in engagement with the openings in platea.

In practice when it is desired to raise the lower sash or lower theuppersash, or both, the operator grasps the milled head of bolt 0 and drawsoutwardly thereon, and after adjusting the sash or sashes releases hishold 7 on the bolt, and the latter, under the action of theplate-spring, is forced inward, causing its inner end to enter any oneof the openings in plate a, thus lockingv the two sashes together, thebolt being firmly held in such position by the pivoted catch orlocking-head D, engaging the outer shoulder on the bolt. In this way thesashes will be firmly locked in relation to each other. A room can besafely ventilated by lowering the upper sash and locking the same inplace. hen it is desired to move the sash or sashesindependent of thelocking mechanism, the bolt is drawn outward and the catch orlocking-head is turned so as to engage the inner shoulder on said bolt,and thus hold the latter retracted. A sash or window fastener thusconstructed is extremely simple, inexpensive, and durable, and is notliable to readily get out of order or become deranged. i

Another and important advantage is that myimproved fastener can bereadilyand easily applied to any and all kinds of windows now in use.

I claim as my invention- The combination, with a window-sash having aplate secured to one side thereof provided with a series of openings, ofa lock comprising a bolt having shoulders in one side, a spring engagingsaid bolt, a casing having an apertured, curved, or bulged portion inone side, a hollow boss projecting up in said casing, a top plate, ascrew for holding the same working in said boss, and the catch orlooking-head pivoted by'said boss and havinga narrowed portionprojecting through the said apertured, curved, or bulged portion,substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses. I

DAVID GUTERMUTE. Witnesses:
